CVE-2025-54767 is a vulnerability identified in Xorux's LPAR2RRD product, specifically version 8.04. The flaw stems from improper use of privileged APIs (classified under CWE-648), which allows an authenticated user with read-only access to kill any processes running on the Xormon Original virtual appliance under the lpar2rrd user account. This means that although the user is not granted write or administrative privileges, they can escalate their capabilities to terminate processes, potentially disrupting the appliance's monitoring and management functions. The vulnerability has a CVSS 3.1 base score of 6.5, indicating medium severity, with an attack vector that is network-based (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and no availability impact (A:N). The issue does not currently have any known exploits in the wild, but the risk remains significant due to the potential for process disruption. The vulnerability is particularly concerning in environments where LPAR2RRD is used to monitor IBM Power Systems virtualization, as unauthorized process termination could impair system visibility and management. The lack of patches at the time of publication necessitates immediate mitigation steps to limit exposure. The vulnerability was published on July 28, 2025, and assigned by KoreLogic.

For European organizations, the impact of CVE-2025-54767 can be significant in environments relying on LPAR2RRD for virtualization monitoring and management, especially those using IBM Power Systems. Unauthorized process termination can lead to loss of monitoring data, delayed detection of system issues, and potential operational disruptions. Although availability and integrity are not directly compromised, the confidentiality impact is high because the ability to kill processes could be leveraged to disrupt security monitoring or management workflows, indirectly affecting system reliability. This could hinder incident response and increase the risk of undetected attacks. Organizations in sectors such as finance, manufacturing, and critical infrastructure that depend on continuous virtualization monitoring may face increased operational risk. The vulnerability requires authenticated access, so insider threats or compromised credentials elevate the risk. The absence of known exploits reduces immediate threat but does not eliminate the risk of future exploitation.

1. Restrict read-only user privileges to the minimum necessary and audit user roles to ensure no excessive permissions are granted. 2. Implement strict access controls and multi-factor authentication to reduce the risk of credential compromise. 3. Monitor process termination logs and unusual activity on the Xormon Original virtual appliance to detect potential exploitation attempts. 4. Isolate the LPAR2RRD management interface within secure network segments to limit exposure. 5. Engage with Xorux for timely patch releases and apply updates as soon as they become available. 6. Consider deploying compensating controls such as application-layer firewalls or endpoint protection to detect and block unauthorized process termination commands. 7. Conduct regular security assessments and penetration tests focusing on privilege escalation vectors within the LPAR2RRD environment.
